PATENT JOHN maar Galena, or FERGUSON, MISSOURI.

Wren CONNECTER.

Application led May 24,

To all whom it may concern:

Be it known that I, JOHN ALBERT'GEISER, a. citizen of the United Statesand a resident of Ferguson, iu the county of St. Louis and State of Missouri, have invented certain new and useful Improvements in lVire Connecters. of which the following is a specification.

My invention is an improvement in wire connecters, and has for its object to provide `means for connecting insulated wires elec-- trically to other wires or to any type of electrical device, without the necessity for removing the insulation from the wires before connecting them.

' Figure 19 is a horizontal section .through one of the metallic plates.

Figure 2O is a similar view through the other plate.

In Figures 1, 2 and 3, the wires 15, 16 an 17 are. connected in T-formation, by means of a metallic conducting element of T-shape. This conducting element, as shown, comprises a T-shaped base 18 havin pairs of knife edges 19 and 20, the knife eges being right-triangular ribs arranged in pairs, the

membersof each pair having their adjacent The knife edgesor ribs 19 are separated attheir. centers by a transverse groove 21, which provides a pair of knife edge ribs for each wire 15, 16 and 17.

In placing the wires they are merely forced into the grooves between the ribs. These ribs are spaced apart a distance corresponding approximately to the diameter of the wire, the arran 'ement being such that there. will bea tight fit when the wire is passed between thev ribs. yThey may be forced into the space between the ribs in any suitable manner, and it will be evident that as the wires are forced into the ribs the insulation will be cut away from the wires, so that the Wires will engage the faces of the ribs directly.

Preferably, one of the ribs 20 has a pin 22 which is adapted to force the wire 17 later` ally, and the other rib has a notch or recess 28 for permitting the wire tomove laterally slightly'. The pin 22 will force the wire laterally, and a portion of the wire 'will enter into the notch or recess, thus forming a positive lock between the ribs 20 and the wire 17.

These knife edges provide strippers for stripping the wire, and the base of the conducting element provides anl electrical connection for the ribs and the wires. rl`he casing is held in a housing of insulating 'materiah consisting of sections 24 and 25,

the complete housingfbeing substantially "Il"- shaped, as shown in Figure 1, and the stem portion of the housing is encircled by a ferrule or ring 26 to clasp the sections 24 and 25 on the casing. In the embodiment of the invention shown in Figures 4, 5 and 6, 'the wires 27 and 28 and 29 to be connected arev arranged inl T-formation, the wires .27 and 28 being in alinement, and the' wire 29 at right angles thereto. The wires 'tre connected by a casingl consisting of a base 30, which has knife edge ribs 130 extending transversely of one end thereof, and corresponding to ribs 19 of Figure 2, and which has similar ribs 31 extending` longitudinally thereof at the opf posite end from the ribs 30,'and corresponding to the ribs 20 of Figure 2.

At the bottom of the groove between the ribs 31 a series-of pins 32 is provided, the said pins being of a .length to extend incassa llO 50 of the constructions through the insulating covering of the wire 29, and the pins are pointed. The casing 30 is enclosed by a sectional housing 33-34 of insulating material, which is held in place by the ring or ferrule 35.

In the embodiment of the invention shown in Figures 7 to 10, a group of wires 36 is connected with a single wire 37. With this p arrangement the connecter casing comprises 10 a base 38 having a series of grooves 39 at one end, the said grooves being parallel and extending' longitudinally of the base' and at the opposite end the base has a pair of knife edge ribs 40 also extending longitudinally 16 of the base, and adapted to receive the wire 37, the grooves 39 being designed to receive the wires 36. Each of these grooves 39 has a series of pins 41, and the groove between the ribs 40 has a pin 42 at one rib and a notch or recess 43 in the other rib, this pin and notch serving t-he same. purpose as the pin 22 and the notch 23 of Figure '2., The

y, casing is enclosed by a sectional housing AS*44--45 which is held on the connecter casing by a ring or ferrule 46.

In Figures 11, 12 and 13, the wires 52 and 53 and 54 are connected by a metallic casing consisting of a base 55 and pairs of knife edge ribs 56, 56a and 57 The ribs 56 a0 and 56El are in alinement, and are separated from each other. by a groove, as shown, which registers with the space between the ribs 57 Alever 58 is pivoted in this groove between the pairs of ribs 56 and 56a, as in- 85 I dicated at 59, and this lever -on one'side of the pivotalj connection 59 lies in the groove between the ribs 57. The other end of the lever is hooked or C-shaped as shown at 60,

and thefree end thereof, which is beveled,

extends into the groove between the ribs 56 and 56a, when the other end of the lever -58 is in the space between the ribs 57 The ribs 56 and 56a and 57 will strip the insulation from the wires 52, 53 andV 54 when 45. the said wires are forced into the grooves wires at a right'an le, but one wire is inserted in the'groove tween the ribs 56 and 56a. As the wire is pressed into the grooves, thev insulation is cut away from the sides, as shown in Figure, 13. The lever 58 is A() swung, as indicated -in dotted lines, in Figure 12, so that the cutting edge atthe end of the portion 60 is moved above the wire and does not interfere withVY the insertion of the wire. After the wire 5234-53 has been placed, the wire 54 is placed between the ribs 57. The lower end of the lever 58 is now forced down to the bottom of the s ace between the ribs 57 and the pointed en of the portion 60 of the lever is forced into close contact with the wire.

In the embodiment of the invention shown in Figures 14 to 20, the connecter comprises a casing of insulating material consisting of similar sections 61, which, when in normal position, constitute a casing of substantially cylindrical form. These sections are grooved on their inner faces to form a bore when they are placed together, and each groove 62 is of greatest depth intermediate its ends', as shown in Figure 15. Metallic conducting elements, indicated at 63 and 64, are arranged in the respective sections of the insulating casing, and, referring to Figures 17 to 20, inclusive, it will be seen that the section 63 is a plate having a series of trans- .verse ribs, indicated at 65, each of which is notched, as indicated at 66, and the notches are in alinement longitudinally of the plate. The edges of the notches are sharpened, as clearly shown in Figure 19, to form cutting edges for stripping the insulation from the wire as the wire is pressed between the ribs. The section 64 is in the form of a plate having transverse ribs 67, and these ribs are arranged so that when the sections are placed vone above the other the ribs 67 will come between the ribs 65. Referring to Figure 17, it will be seen that six ribs' are provided on the conducting element 64, two being at the center andthe others at the ends, and the two central ribs are nearer together than are the other ribs.` The element 63 also has sixribs, and thetwo central ribs are nearer together than the others. The central ribs of the sections 64 are adapted to engage between the two central ribs of the section 63, as shown in Fi re 15, in order to bend down the ends of t evwires 68, which are arranged between the conducting elements.

The recesses or grooves 62 in the 'casing section 61 are shaped to receive the conducting elements 63 and 64, and the wires are laid in these grooves and-on the element 63. When the upper section of the casing is placed on these wires 'and pressed downwardly, the metallic wire filament inside the insulation will bepressed down into the notches 66, and the ribs 67 which are sharp edged will cut through Ithe insulation between the ribs 65. The edges of the notches 66 on the ribs 65 will also cut through the insulation and an electrical connection will be established.

The casing sections are held together on the wires by means of a metal sleeve 68.

This sleeve is of a size to fit over the sections.

when they are abutted and it has .intermediate its ends a circumferentially. extendingtongue 69 which isadapted to engage inv iso a circumferentially extending notch in one of thesections 61 to prevent the sleeve from movement longitudinally of the sections. The tongue is resilient so that the sleeve may be detached when desired. This engagement of the sleeve is shown in Fi ure 16, v
